One big accessibility improvement in SwiftUI comes in the form of named controls. Nearly all controls and some non-interactive views (see Images) can take a Text view as part of their view builder. The purpose of this is to tie the meaning to the control.

Toggle(isOn: $updates) {
 Text("Send me updates")
}

Imagine a UIKit layout with a UISwitch control. We’d most likely right align the switch, and provide a text label to the left. Something like this.
